USSD Codes for 4.2.1 - T-Mobile, Samsung Galaxy SIII

Because of the recent news of making it illegal to unlock phones I tried to use the *#simlock# code to check to see if my phone (T999) was unlocked. I keep getting the "Connection problem or invalid MMI code" so I tried a bunch of other codes which also didn't work. Is this because I'm running 4.2.1 (AOSP)? I remember when I had 4.0.4 USSD codes worked normally.

you need to be stock to unlock your phone, the codes dont work on aosp.

I did the sim unlock on my phone a few months ago when it was just stock rooted, I'm not entirely sure if it worked then. Would that still apply now and is the only way to check is with a different carrier's sim?

from what i understand, yes. when you unlock the sim there is nothing that says "it's unlocked!" so yeah you have to use an AT&T sim and see if you can make a call
and it sticks after a flash, it's not rom dependent, you just have to be stock to unlock it, then you can flash whatever you want

Foreign SIM doesn't prompt for unlock code -- how to unlock?

I have a SaskTel Samsung Galaxy S3 (SGH-I747M, baseband version I747MVLLE8) that is locked, and I want to unlock it. But when I insert a foreign SIM (from AT&T) I get no prompt for an unlock code. Instead it just says "No SIM card. Emergency calls only." I've contacted several of the online unlock code suppliers and they say without this prompt I can't unlock the phone. I've also tried to enter variations of the *7465625* code, but they do nothing at all. SaskTel says they don't provide unlock code. This despite the fact that I purchased the phone outright, and have no contract with them. Am I totally hooped, or is there some way I can get this phone unlocked?

try another SIM, maybe the one you're using is borked.
Try this
#7465625*638*# (Insert Network Lock Keycode)

Possible, but I doubt it, since it works just fine in another phone. In any case I don't have another one to try.
Misread
#7465625*638*UNLOCKCODE#
I noticed in an earlier post, the place of the unlock code was after the #, it should be before. On the right track though. Probably just a typo.
unless you already tried that.

That and probably every variation of it I can think of! I am wondering though, is this code internal only to the phone, or does it go to the cellular network? When I do type it, it does nothing, though if I send it I get an "Invalid USSD" message returned from the network.

this code doesn't work on the LTE variants of the SGS3. most of the multi-stage codes (####*###) don't work, you just end up with an error.
Correct as stated. Additionally, if you have a foreign micro sim, and you are not on a stock ROM, the unlock screen prompt will not show. I was running AOKP, and could not get the prompt to show, so I flashed back to stock, unlocked phone, then flashed back to AOKP, bc TW sucks!

This is what I was starting to suspect. Can you refer me to a good, really clear step by step procedure to do this? I've never done this with a phone, and since I live in a small town, I doubt I can find anyone to help me here. So a step by step would be nice. Thanks.

are you on a stock ROM?
i have a i747M and unlocked it with the at&t micro sim, so i know it works,
did u cut ur at&t sim down to size ? maybe u did it wrong and it wont recognize, or ur sim slot is ****ed up ....
ur best bet right now is to try another micro sim
Ok, I've now got my phone rooted. Can someone suggest how I can get the ROM set so that it will allow me to enter the unlock code when I insert a foreign SIM.
There's a 3rd potential method that hasn't been mentioned on here that we see working for most Samsung handsets. In fact, for some Samsung handsets (usually older ones) it is the only unlocking method that will work.
It is:
1. Turn on the phone with a non accepted or accepted SIM card inserted
2. Type #0111*CODE# replacing CODE with your network unlock code
However, if your service provider lock is active, then you'll need to use the code #0133*CODE# instead.
All unlocking methods (once you have the unlock code) are available here: http://www.mobileunlocked.co.uk/samsung-instructions.asp
Hope that helps.
Did you manage to unlock?
I'm facing the exact same issue. My S3 doesn't show the network unlock prompt when I insert a foreign SIM. Mine is locked to AT&T. It's also SGH-I747 model
You could try and unlock your phone as per this thread:
http://forum.xda-developers.com/showthread.php?t=2033225
Then try the SIM card after the phone is unlocked.
Oh, I believe this only works on Stock ROMS.

Follow the link Tybalt quoted, you will unlock your phone and the sim won't ask for an unlock code because well, it's unlocked.... Follow the instructions, you need to be on JB 4.11 for this to work, some have had success on custom roms but not many....you don't need to root to do this and make sure when you see the success code you have 40 at the end not 30... i did this a couple times... 30 I think basically means you have locked it again ... and in the instructions when it says wait 30 or 60 seconds... you really do have to wait.. don't be impatient....it's a huge thread with many many successes.....
Samsung Galaxy S3
I have the same issue but I have a sgh-i747 Samsung galaxy S3 i brought it to koodo and was told it was a compatible phone with the company when unlocked. The problem/question i have is When i insert my new simcard the screen will not display any prompt to input a unlock code. It just says emergency calls only or unregistered sim. I inserted my sim card into another s3 same model, software versions, different provider, and the phone asked for the unlock code right when powered on. So i tried and flashed a new firmware but its doing the same thing.
I called koodo and they gave me instructions to create a new apn of Koodo SP it did not make my phone prompt me for an unlock code.
When i send an email to any website about unlocking my phone they advice me not to purchase there product if my phones not prompting me for a unlock code that will it more then likely not work.
I've seen methods online of using these to input an unlock code "#0111*UNLOCKCODE#" or "#7465625*638*UNLOCKCODE#" but when i tell the unlock website this information this still tell me not to purchase there product and i mean many numerous websites. I do not want to buy an unlock code only to try to input it with these methods and have it not work. Which i highly dought it would because the normal 7465625 command doesnt work either.
I also tried this factory unlock and it did nothing
PLEASE HELP!?!?

Thank you so much for this!
Whenever I typed any variation of the #7465625 code I would get the "emergency calls only" message. #0111*CODE# did the trick!
The provider didn't even know this, the best they could come up with after numerous calls to their hotline is that the phone was broken and/or that the SIM card was badly inserted, thus I should mail them the phone to the other side of the country for unlocking. Would they even have known how to do it over there?
My grandma says thanks!

[Q] Enter SIM unlock code without a different carrir sim?

all else fails i will just print out the text where at&t texted me the code. just would like it done before.

You need a SIM from a different carrier to use that method. Also, check out this thread:

Need help unlocking

I need to unlock my wife's S3 and I got the unlock code from AT&T but when I try to do it, it says unsuccessful. The phone is completely stock not even rooted. Can anyone help cause AT&T is useless?
Does the imei match the imei on the phone's printed label?
Yes it does
When you insert a non-ATT sim, you get the prompt to enter the unlock code? If you do and you enter the code provided by ATT based on the phone's imei, sounds like ATT may have given you the wrong code.

Yes then it gives me and sim unlock unsuccessful. I am getting sick and tired of sitting on hold with them
I'm not sure if the s3 gives you a limited number of tries to unlock it but I would not attempt more than 2 attempts each day.
I assume you confirmed the imei # with ATT? Is it possible the phone is hard-locked to ATT? Did ATT give you any other codes such as unfreeze codes, PUKs, etc.?
i know you said stock , unrooted. dont you have to be on 4.1.1 to unlock? prob. are, just asking.
err on the side of kindness
What ROM is on your phone? If it is 4.1.1 or 4.1.2, you could try using the free unlock method.
I'm having the same problem here. Received a code from AT&T on Oct 26th and they're still trying to figure out why it doesn't work. Bought the locked phone at BestBuy and never touched it until I tried to use the code they gave me.

If you were on 4.1.1 or 4.1.2 and the code didn't work, you could revert back to stock 4.1.1 and unlock the phone for free. Since you're on 4.3, you can only unlock the phone with an unlock code. Seems strange that the unlock code doesn't work. Did you confirm you phone imei and the imei you submitted to ATT?

Yes, I checked everything. Today I spent almost an hour on the phone with them trying to figure out the problem. They even called Samsung and they didn't know what was wrong either.

I read that the phone displays a message when that happens, and none has been presented so far... It always asks me for the network unlock code.
Problem solved
To whoever is going through the same trouble. This is not the "unlock it for free" method, for you will need to insert the unlock code
For Samsung Galaxy S3, S4 and Note 2. Device must be updated to the latest firmware.
Phone MUST prompt for the code. This is the "release method" on the phone(s).
a. Go to the Dial pad and dial *#197328640#
b. Click on number [1] UMTS > [1] Debugging screen > [8] Phone Control > [6] NETWORK LOCK
c. You will see 3 options. Click on number [1] Perso Sha256 INFO, the screen will change slightly
e. Hit the MENU button then when the menu pops up carefully hit BACK to return to the previous screen
f. Click on number [2] Perso Sha256 ON, the screen will change again to a one line message
g. Restart the phone on the screen by holding the power button and click RESTART
h. When the phone prompts for the unlock code simply enter the unlock code
END

[Q] Pls Help! Need to determine unlock status asap. Also, USSD codes failing

Hi.
I am unsure if my phone is unlocked and can proceed with porting my number over to Metro PCS. Please help me with advice how to proceed. I decided to move my service to Metro PCS since they are now a Tmobile company and after lots of research, I found that I can use my current phone/software as long as it was unlocked. I recently purchased my Galaxy s4 second hand and assumed it was not unlocked. I had immediately rooted it and flashed a new rom (Insane Kitkat 4.4.4). The phone has been working well. I already have requested and have my unlock code from Tmobile.
When I went to the Metro PCS store to port over my number, the phone did not request an unlock code when inserting their Metro PCS sim card (not activated). They said that my phone may already be unlocked or that it may not need to be unlocked since Metro is now owned by T-mobile. They stated that it may work if they go through the entire registration process, port over my number and activate it but that it would be a gamble. If it did not work, then I would not be able to go back and reactivate my sim immediately with Tmobile since it would then be in deactivated status with them.
I tried to find out if it is already unlocked by *#7465625# but my phone will not run this or any other USSD codes to verify. I keep getting errors when trying any USSD codes. A message says 'USSD code running' then "unable to process request".
A friend of mine has an activated Galaxy S4 on Metro PCS and I tried inserting her sim card to prompt for the unlock code but my GS4 just booted normally then showed 'not registered on network'. It did, however, have cellular signal bars. When I inserted my Tmobile sim into her GS4 it did ask for the unlock code normally.
I am at a loss now..
funny, I like to know if there is a way to check carrier unlock status for simcard without having to put a simcard in.
T-Mobile phones work with metropcs without the need to unlock
Could the custom rom be suspect?
Maybe need a stock rom to get carriers sorted out, then go to custom roms.

I ended up contacting Tmobile and they stated that the phone showed unlocked status already but I think you are correct. I wasn't aware they could tell me this. It was very fast and super easy to find out.
I have the phone working great on Metro PCS now. USSD codes still failing though...

[Q] Having trouble unlocking phone from Wind

Man, what a nightmare...
I moved from Vancouver to California in February, and I've been trying to unlock my phone from Wind ever since. They provided me with an unlock code that doesn't seem to work. Then, after waiting 30 days for them to get me a new code, they gave me the same one. At this point, I doubt that the code is a mismatch to my IMEI, but it's just not working...
Here's the facts:
I have a SGH-T999V running 4.4.2. When I put in the T-Mobile sim card that I'd like to use and then try to put in the unlock code, I get an error message saying that the unlock code was unsuccessful.
Here are the questions that I have:
Do I need to be on the Wind Network to have the unlock code work? I selected T-Mobile as the network operator ever since I moved down to California.
It seems like other people with my version of the phone have had similar issues...is there a solution to this problem?
Can the fine, fine people of this forum help?
This has been a problem since 4.3 with some Samsung devices. Only thing I can suggest is try regionlock away from chainfire to see if it will unlock, which is probably unlikely. Make sure you are on stock firmware with stock kernel

Hi Andrew, it just says "Network unlock request unsuccessful."
I tried rooting my phone and using regionlockaway, which said that the patch was successful, but it seems that wasn't the solution.
It's pretty frustrating since I paid Wind for the unlock code, but it won't unlock my phone! Do you think that there is anything else I can do?

Welp, I'll give it a try, but I've seen in other posts that people have been given the runaround by Samsung, who say, "This is because of how Wind locked your phone, can't help you."
I'll update this post with my progress, in case other people are having the same trouble.
